SAFETY DEVICE FOR BUZZ-PLANEBS.

To al?, whom t 'muy concern.'

Be it known that LYDLoN Mazunnrfrn, citizen ot the United Statedresiding at Alameda, in the county of Alameda and *4t-ate of"Lalitoi-nia. have invented certain new and useful lniprovements inSafety Devices for Buzz-laners, ot which the following is aspecification.

This invention is a device for guiding` the work i aratus.

Y @ne ot' the objects ot' the invention is to provide a movable guardpositioned over tie knives of a buzz planer or similar apparatus in suchmanner that the hands of the operatorl are prevented from coming incontact with the knives. 3 A further Objectis to provide a guard of thecharacter referred to "which will accommodate itselt' towork otdifferent widths.

The invention will be hereinafter fully set itforth and particularlypointed out in the claim.

ln the accompanying drawings Figure l is a top plan view or" a planerwitlrthe guard in position. Fig. 2 is a side elevationV of the same.Fig. 3 is an end elevation, and 4C is an enlarged view of the guardmounting.

Tr`eiierring to the drawing, l indicates the base of a buzz planer of awell known type7 and the rotating cylinder' which carries the knives.the saine being driven by a suitable source et power 3. through the belt3. A guide 4 isprovided against which the mai is forced while beingworked. in a on a buzz planer or similar apterial manner well known.

Pivoted to the planer table 6 is a guard 5. said table having Van angleplate i'. provided with a boss 8 through which the pivot rod 9 passes.Said rod 9 is provided with a plate 'l0 which is attached to the bottomot the .Quard in suitable manner. such as by means oi the screws il.rlhis construction enables the guard to be moved in a horizontal plane.and by platingshims between the boss 8 and the plate l0. .he guard maybe raised to any height above the table, as is shown by e dottedposition 2. In case the guard 5. by reason of its weight should sag, aset screw 19 has been provided in the plate and has one end thereof inabutting engagement with the guard. By adjust- Specification of LettersPatent. Patented Maf. 15, 1921.

Application filed .Tune 4.-, 1918.

Serial No. 238,130.

nient of said screw the guard will be elevated or adjusted relative tothe plate to take up the sag. In order to keep a constant pressure on atimber being operated upon, a weight l2 is provided, which is secured tothe guard by means orn a cable i3, fastened to i hook 14C Von theunderside of the guard.

The cable passes under the table 6, over a l Vpulley l5 anddown to theweight l2.

the weight keeping the guard always againstl the timber and over therotating knives, protecting the operator. `Vhen the timber has s passedthrough the machine, it is placed on top or" the guard and returned toits first po-v sition, the hands of the operator never coming near theknives. To compensate for warping of the guard, a set screw 19 is putthrough the plate lOyand enables the guard 5 to be raised if desired. Y

Having thus explained the nature Aof the invention. and described anopera dive man# ner 01"' constructing and using the same althoughwithout attempting to set forth all of the forms in which it may bemade, or all ot the forms of its use. what is claimed is -l guard forplaning machine, comprising an attaching bracket. a plate secured bvAastening elements to one end of the guard, a depending spindle rigidwith' said plate and journaled in said bracket for rotatably supportingthe guard, an adjusting screwV threaded in said plate and engaging saidAguard. said set-screw being located in the plate relative to saidfastening elements and said guard `to adjust the latter relative to theplate in case of sagging, said spindle being elongated and slid able insaid bracket to permit the insertion of shims to elevate the guardrelative to said bracket.

ln testimony whereof I aiiix my signature.
